Honeywell ST3000 Honeywell Smart Differential Pressure Transmitters

Key Features:

1. Differential Pressure Measurement:

   • The ST3000 transmitter is designed to measure the difference in pressure between two points, often used in applications like flow measurement, level monitoring, or filter monitoring.
   • It provides precise measurements of the differential pressure in various industrial processes.

2. Smart Transmitter:

   • The “smart” designation means it incorporates digital communications, typically supporting protocols like HART (Highway Addressable Remote Transducer), allowing easy configuration and diagnostics through a control system or handheld communicator.
   • Smart transmitters have the ability to provide additional data beyond basic measurement, including diagnostics and health status of the transmitter.

3. Accuracy and Range:

   • The ST3000 transmitters are known for their high accuracy and stability over a wide range of pressures.
   • It can measure low and high differential pressures with high precision, which is crucial in process control systems.

4. Rangeability:

   • The ST3000 offers excellent rangeability, making it suitable for different process conditions where the differential pressure might vary widely.

5. Applications:

   • Flow Measurement: When used with orifice plates, venturis, or flow nozzles to measure flow rate based on differential pressure.
   • Level Measurement: Commonly used in tank level measurement, where the differential pressure between the bottom and top of the tank is measured to determine the level of the liquid.
   • Filter Monitoring: Helps to monitor the performance of filters by measuring the pressure drop across the filter media.

6. Robust and Reliable:

   • The ST3000 transmitters are built to withstand harsh environments and are used in chemical, petrochemical, oil and gas, power generation, and water treatment industries.

7. Digital Communication:

   • The HART protocol enables the transmitter to provide a digital signal, allowing remote configuration, calibration, and troubleshooting via handheld devices or a control system.

8. User-Friendly Interface:

   • Local display and easy-to-use interface for field setup and diagnostics.

Applications:

• Oil and Gas: For monitoring flow rates and pressure differences in pipelines, compressors, and wellheads.
• Chemical Processing: In reactors, distillation columns, and pipelines to measure pressure differentials.
• Power Generation: For measuring pressures in turbines, boilers, and heat exchangers.
• Water and Wastewater Treatment: Monitoring level and flow in tanks, filters, and pipelines.
• HVAC and Building Automation: For maintaining airflow and pressure levels in large buildings and industrial systems.
